Abstract
The invention discloses a screw of a building scaffold. The screw comprises a bolt, a gasket and a nut base body. The bolt comprises a bolt head, a threaded rod and a fixed block. The bolt head is formed by cutting off regular triangular prisms from the upper ends of the two sides of a cuboid respectively. A rib is arranged at the lower portion of the bolt head. The fixed block is installed on the left side of the rib. The threaded rod is arranged below the rib. A first thread is formed in the threaded rod. The gasket comprises a supporting block, a stop piece and a second thread. The supporting block is arranged on the front end face of the gasket. The stop piece is arranged on the right end face of the gasket. A first thread through hole is formed in the center of the gasket. A second thread is formed in the inner wall of the first thread through hole. A second thread through hole is formed in the center of the nut base body. A third thread is formed in the inner wall of the second thread through hole. The gasket and the nut base body are arranged on the bolt, and a fastener and a steel pipe can be fixedly and compactly connected and prevented from falling during work.
